No Mg 2+ ion is a monatomic ion, it is made up of only one Mg atom.
What is a polyatomic ion?
Polyatomic ions are covalently bonded groups of atoms and having a positive or negative charge caused by the formation of an ionic bond with another ion. Compounds formed from such a combination of ions are polyatomic ionic compounds.

Ans: We can calculate the total number of protons in a hydroxide ion by adding up the number of protons in one hydrogen atom and one oxygen atom:
Why do monatomic ions have a net charge?
The ion has a net charge over it because the total number of electrons is not balanced by the total number of protons in the nucleus.
